1. A photonic circuit, comprising:
one or more photonic input gates having one or more inputs to receive one or more photonic input signals, the one or more photonic input gates configured to generate one or more photonic signals based on the one or more photonic input signals;
a first set of one or more photonic gates coupled to one or more outputs of the one or more photonic input gates, the first set of one or more photonic gates configured to generate one or more intermediate photonic output signals based on the generated one or more photonic signals;
at least one nonlinear amplitude thresholder coupled to at least one output of the first set of one or more photonic gates, the at least one nonlinear amplitude thresholder configured to generate at least one photonic thresholding signal based on at least one of the one or more intermediate photonic output signals, the at least one nonlinear amplitude thresholder operating in at least one of a first operating regime, a second operating regime and a third operating regime; and
a second set of one or more photonic gates coupled to at least one output of the at least one nonlinear amplitude thresholder, the second set of one or more photonic gates configured to generate one or more photonic output signals based at least in part on the at least one photonic thresholding signal.
